| Abstract: | According to the property of the general linear least squares problem in R~n,the bisymmetric optimal approximate solution of matrix equation A~TXA=C is studied by using CCD and GSVD of matrix pairs.This method is also used to develop the optimal approximate solution of the matrix equation AXB CYD=E or AXA~T BYB~T=C. |
